A building system comprises one or more panels with one or more “Z-shaped” edges. The panels may connected to each other through interaction of the corresponding shaped edges. In addition, a building component comprises upper and lower surfaces and first and second lateral ends. One or more of the building components may be connected together through engagement of the second lateral end of a first building component with the first lateral end of a second building component. Through this connection, vertical forces on the building components are transferred laterally.
